A year later

If a cavity developed underneath a top molar sealant, could an anticavity mouthwash have prevented such cavity if even before such cavity even developed in the first place? If one year before when such cavity wasnt there would have an anticavity mouthwash have been able to have prevented such certain cavity that developed not on top of sealant but underneath it instead? Last year i went to see my dentist and didnt have any cavities but i wasnt using an anticavity mouthwash either! I saw my dentist a year later and there was a cavity virtually where the sealant is...
